  The present invention relates to a digital camera having a display device, and more particularly to a digital camera having a control device capable of changing the size of an image displayed on the display device.

Conventionally, a digital camera including two display devices for displaying an image is known. A through image that is a subject image incident from an imaging lens is displayed on one display device, and a captured image recorded in a digital camera and a partial enlarged image of the through image are displayed on the other display device. A user performs shooting by referring to a desired portion by individually operating images displayed on two display devices (Patent Document 1).
JP 2005-86283 A

  However, when the user desires to refer to a plurality of parts in the photographed image, the two photographed images must be enlarged or moved one by one in order to display the desired part on the display device at a desired display magnification. Therefore, an operation burden is imposed on the user.

  The present invention has been made to solve this problem, and it is an object of the present invention to obtain a digital camera that facilitates reference of an image by simultaneously enlarging images displayed on a display device.

  The digital camera according to the first invention of the present application is input by a display device that simultaneously displays a plurality of images, a display magnification input unit that inputs display magnifications of the plurality of images displayed on the display unit, and a display magnification input unit. And a display magnification control device that simultaneously changes display magnifications of a plurality of images displayed on the display unit at substantially the same rate of change according to the display magnification. Substantially the same rate of change means the same rate of change within a range where the user can recognize that the rate of change is the same.

  The digital camera further includes image selection means capable of selecting an image from a plurality of images, and when the image selection means selects a plurality of images from the plurality of images, the display magnification control device uses the display magnification input means. It is preferable that the display magnification of the selected image is simultaneously changed at substantially the same rate of change according to the input display magnification.

  Further, when the maximum display magnification is set as the display magnification, the image selection means selects a plurality of images from a plurality of images, and when any one of the plurality of images is displayed at the maximum display magnification, the display magnification control is performed. The apparatus preferably does not change the display magnification of the selected image.

  Further, when the minimum display magnification is set as the display magnification, the image selection means selects a plurality of images from a plurality of images, and when any one of the plurality of images is displayed at the minimum display magnification, the display magnification control is performed. The apparatus preferably does not change the display magnification of the selected image.

  The digital camera further includes image selection means for selecting any one image from a plurality of images, and the display magnification control device displays the display magnification of the image selected by the image selection means by the display magnification input means. It may be possible to change it according to.

  The display device may include as many display areas as one image to display, and the display magnification control device may change the image display magnification based on the center of the display region.

  An image display system according to a second invention of the present application further includes a display device provided outside the digital camera and provided with a receiving device for receiving an image signal from the digital camera, and an output device for outputting the image signal to the display device. The digital camera according to claim 1 is provided.

  According to the present invention, a digital camera that easily enlarges an image displayed on a display device and easily refers to the image is obtained.

  Hereinafter, an embodiment of a digital camera according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is an external view of a digital camera to which an imaging lens is attached.

  The configuration of the digital camera 100 and the imaging lens 20 will be described with reference to FIGS.

  Outside the digital camera 100, a display device 120 that displays a captured image, a release button 111 that is pressed when shooting, a rear operation dial 112 that operates the digital camera 100 by a rotating operation, a cross key 113, and various buttons 114. 115, 116, 117, the front operation dial 119, an output terminal 141 for outputting an image signal to an external display device, a card slot 140 for inserting an image recording medium, and an imaging lens 20 for visually recognizing a subject. An optical finder 130 is mainly provided.

  A CPU 150 is provided inside the digital camera 100. A flash memory 161 is connected to the CPU 150, and a program for operating the CPU 150 is stored. When the power of the digital camera 100 is turned on, the CPU 150 reads a program from the flash memory 161 and executes it. The aperture of the diaphragm 22 attached to the imaging lens 20 is controlled by a diaphragm driving circuit 159. The subject image incident on the imaging lens 20 is reflected by the return mirror 154 and guided to the optical viewfinder 130. The user visually recognizes the subject incident on the imaging lens 20 via the optical viewfinder 130.

  When the user presses the release button 111 halfway, an imaging preparation signal is transmitted from the release button 111 to the CPU 150. The CPU 150 that has received the imaging preparation signal controls the photometry circuit 151 to measure exposure. The exposure information calculated from this exposure is displayed on an in-finder display device (not shown) provided in the optical viewfinder 130. The user determines shooting conditions with reference to the exposure information. The shooting conditions are, for example, the shutter speed, the aperture opening, and the ISO value, and are input to the digital camera 100 by rotating the rear operation dial 112. When the user rotates the rear operation dial 112, a resistance, that is, a click feeling is given for each predetermined angle. The CPU 150 controls the shutter speed, aperture opening, ISO value, and the like using the input shooting conditions.

  When the release button 111 is fully pressed, a shooting operation is performed. In the photographing operation, the process from the transmission of the signal to each circuit by the CPU 150 to the transmission of the image data to the CPU 150 is performed. More specifically, the CPU 150 transmits signals to the aperture driving circuit 159, the mirror driving circuit 153, and the shutter driving circuit 155. The aperture drive circuit 159 adjusts the aperture 22, the mirror drive circuit 153 raises the return mirror 154, and the shutter drive circuit 155 opens and closes the shutter curtain 45. As a result, a subject image is formed on the image sensor (CCD) 157.

  The image sensor 157 transmits the image data to the A / D converter 158. Since the aspect ratio in the light receiving surface of the image sensor 157 is approximately 2: 3, the aspect ratio in the image data is also approximately 2: 3. The A / D converter 158 converts the imaging data into image data and transmits it to the CPU 150. Next, the CPU 150 performs image processing while temporarily recording the image data in the flash memory 161, and outputs an image file. In image processing, adjustment of color tone of image data and JPEG compression are performed. The digital camera 100 includes a position sensor 118 for determining whether its own state is in the vertical position or the horizontal position. The position sensor 118 transmits to the CPU 150 a signal indicating whether the digital camera 100 is in the vertical position or the horizontal position when the release button 111 is fully pressed. In the image processing, the CPU 150 writes a signal indicating whether the image is in the vertical position or the horizontal position as Exif information in the image file. The image file is recorded on the image recording medium 162 inserted in the card slot 140. The image recording medium 162 is, for example, an SD card, a compact flash (registered trademark), or the like. These devices operate with electric power supplied from the battery 170.

  The captured image of the image file recorded on the image recording medium 162 is displayed on the display screen 121 of the display device 120 when the user operates the playback button 115. The aspect ratio of the display screen 121 is approximately 3: 4. When the playback button 115 is pressed, the digital camera 100 operates in the playback mode. In the playback mode, the captured image of the image file with the latest shooting date is displayed first. Then, when the left direction mark 113a marked on the cross key 113 is pressed, the photographed image of the image file with the newest photographing date is displayed. When the right direction mark 113b marked on the cross key 113 is pressed, a captured image of an image file with an old shooting date and time is displayed.

  When the captured image is displayed on the display screen 121, the CPU 150 reads the Exif information of the image file and determines whether the captured image is captured in the vertical position or the horizontal position. When the image is taken in the vertical position, a photographed image rotated 90 ° to the left is displayed on the display screen 121. When the image is taken in the horizontal position, the image is displayed on the display screen 121 without being rotated.

  As described above, the aspect ratio of the display screen 121 is 3: 4 and the captured image is 2: 3. Therefore, the captured image captured in the horizontal position is displayed on the display screen 121 so that the length of the long side matches the length of the long side of the display screen 121. The display magnification of the photographed image at this time is set to 1. On the other hand, since the captured image captured at the vertical position is displayed by being rotated 90 ° to the left, there are areas where no image is displayed on the left and right of the captured image. The display magnification at this time is 0.75 times. Hereinafter, the captured image captured in the horizontal position is referred to as a lateral captured image, and the captured image captured in the vertical position is referred to as a vertical captured image.

  When the pre-operation dial 119 is rotated rightward while the captured image is displayed on the display screen 121, the captured image is sent, that is, the next captured image is displayed on the display screen 121. When the image is rotated leftward, the captured image is returned, that is, the previous captured image is displayed on the display screen 121.

  When the rear operation dial 112 is rotated to the right while the captured image is displayed on the display screen 121, a part of the captured image is enlarged and displayed. The maximum magnification is 32 times. When the rear operation dial 112 is rotated leftward in a state where the photographed image is enlarged, the photographed image is reduced. The minimum magnification is 0.75 times for both vertical and horizontal captured images. For each click feeling of the rear operation dial 112, the enlargement ratio is increased or decreased by a predetermined step. Enlargement / reduction is performed based on the center of the display area 121. That is, the center of the captured image displayed on the display screen 121 is the same before and after enlargement and reduction.

  Further, when the cross key 113 is operated in a state where a part of the photographed image is displayed in an enlarged manner, the display area can be moved. Pressing the up direction mark 113c marked on the cross key 113 presses the display area upward, pressing the down direction mark 113d downwards, pressing the left direction mark 113a presses the left direction, and presses the right direction mark 113b. Then it moves to the right.

  The digital camera 100 can display two captured images on the display screen 121 at a time. The operation of the digital camera 100 when displaying two captured images at once will be described with reference to FIGS.

  FIG. 3 shows an operation of selecting one photographed image from two photographed images displayed on the display screen 121 and changing the display magnification thereof. It is possible to switch from a state where one captured image is displayed (uppermost) to a state where two captured images are displayed by operating the Fn button 114, and the display magnification is changed while one captured image is selected ( Bottom).

  FIG. 4 shows an operation of selecting all captured images displayed on the display screen 121 and changing their display magnification. Each photographed image is selected in a state where it is displayed at a different display magnification, and at the same time, it is scaled at substantially the same rate of change.

  FIG. 5 shows an operation of selecting all photographed images from two photographed images displayed on the display screen 121 and simultaneously changing their positions on the first and second display areas. In the upper right block 5A, the two captured images both reach the moving end, and the other blocks show a state in which only one captured image has reached the moving end.

  The display screen 121 has a first display area 122 and a second display area 123 that are formed by being divided into left and right halves, and a first captured image 124 is displayed in the first display area 122. The second captured image 125 is displayed in each display area 123.

  A means for displaying two captured images from a state where one captured image is displayed on the display screen 121 will be described with reference to FIG. When one captured image is displayed on the display screen 121 at a display magnification of 1 times, when the Fn button 114 is pressed, a function selection screen is displayed on the display screen 121. When the user selects to display a plurality of captured images using the cross key 113 on the function selection screen, the same captured image is displayed in the first and second display areas 122 and 123. When one captured image is enlarged, the same captured image is displayed in the first and second display areas 122 and 123 by pressing the Fn button 114. In any means, the display magnification of the photographed image displayed in the first and second display areas 122 and 123 is the same as the display magnification of the photographed image displayed immediately before.

  The user can select the first and second display areas 122 and 123 to change, enlarge, reduce, and move the captured image displayed in the selected display area. The selected display area is surrounded by a green selection frame 126. In FIGS. 3 and 4, the selection frame 126 is indicated by a broken line. When the OK button 117 is pressed while the captured images are displayed in the first and second display areas 122 and 123, the selection frame 126 becomes the first display area 122, the second display area 123, and both display areas. Move in the order.

  When the captured image is displayed in the first and second display areas 122 and 123, the selection frame 126 is in a state where the second display area 123 is selected. The user presses an OK button 117 to move the selection frame 126 and select any display area. Then, the photographed image displayed in the display area selected using the front operation dial 119 is sent. The display magnification of the photographed image newly displayed by sending the photographed image is the same as the display magnification of the photographed image already displayed. For example, when the display magnification of the captured image already displayed is 1.2 times, the display magnification of the newly displayed captured image is also 1.2 times. Since the images are displayed at the same magnification, it is easy to grasp the size of the subject image.

  When the rear operation dial 112 is rotated left and right with the first display area 122 selected, only the first photographed image 124 can be enlarged or reduced. When the rear operation dial 112 is rotated left and right with the second display area 123 selected, only the second photographed image 125 can be enlarged or reduced.

  Further, when the cross key 113 is operated while the first display area 122 is selected, the first display area 122 moves with respect to the first captured image 124, and the cross is displayed with the second display area 123 selected. When the key 113 is operated, the second display area 123 moves with respect to the second captured image 125. The first and second display areas 122 and 123 press the upper direction mark 113c, the lower direction mark 113d, the left direction mark 113a, and the right direction mark 113b in the same manner as when one captured image is displayed. To move in each direction.

  As shown in FIG. 4, when the rear operation dial 112 is rotated in a state where two left and right vertical photographed images are selected, the two photographed images are both enlarged and reduced. Enlarging / reducing is performed by increasing / decreasing both display magnifications in a predetermined step with reference to display magnifications when two photographed images are selected. For example, when the display magnification of the first captured image 124 is 0.75 and the display magnification of the second captured image 125 is 1.7, the rear operation dial 112 is rotated rightward by 9 clicks. As a result, the display magnification of the first photographed image 124 is changed from 0.75 to 9 times increased by 9 steps, and the display magnification of the second photographed image 125 is changed from 1.7 to 16 times increased by 9 steps. To do. The change rate for one step is, for example, in the range of about 1.16 times to about 1.3 times. This range is determined on the basis of √√2 (= 1.189) times.

  For example, when one of the captured images reaches 32 times, the display magnification of the two captured images is not increased. If the display magnification of the first captured image 124 is 16 times when the display magnification of the second captured image 125 is 32 times, the first captured image 124 is not enlarged beyond 16 times.

  Similarly, when two horizontal shot images, or a vertical shot image and a horizontal shot image are displayed in the first and second display areas 122 and 123, the two shot images are both enlarged and reduced. . For example, when one of the captured images reaches 0.75 times, the display magnification of the two captured images is not reduced. If the display magnification of the second photographed image 125 is 1.7 times when the display magnification of the first photographed image 124 is 0.75 times, the first photographed image 124 is from 1.7 times. Is not reduced.

  This makes it possible to always display the same size of the subject displayed in the first and second display areas.

  When the cross key 113 is operated while the first and second display areas 122 and 123 are selected, the first and second display areas 122 and 123 are simultaneously moved by the same movement amount (see FIG. 5). This movement amount is calculated by the number of pixels of the display screen 121 on which the captured image is displayed. The operation is performed by pressing the up direction mark 113c, the down direction mark 113d, the left direction mark 113a, and the right direction mark 113b as in the case where one image is displayed. Note that the amount of movement is the same even if the display magnifications of the first and second captured images 124 and 125 are different.

  Movement limit positions are determined in the first and second display areas 122 and 123. The movement limit position is the center position of each side of the first and second display areas 122 and 123.

  When the right direction mark 113b is pressed, the second display area 123 moves in the direction of the arrow Da, and the central position of the bottom 123a of the second display area 123 and one side 125b of the second photographed image 125 are orthogonal to each other. Then, the movement of the second display area 123 in the arrow Da direction is restricted. On the other hand, the movement of the first display area 122 that has not reached the movement limit position is not restricted. The first display area 122 moves in the direction of the arrow Da until the center position of the base 122a of the first display area 122 and the one side 124b of the first captured image 124 are orthogonal to each other. The same operation is performed in the upward direction, downward direction, and left direction.

  As a result, the display image does not disappear from the first and second display areas 122 and 123. Further, by setting the movement limit position as the center position of one side of the first and second display areas 122 and 123, the user can easily recognize the end portions of the first and second captured images 124 and 125. it can.

  When the green button 116 is pressed while the first and second photographed images 124 and 125 are displayed, the first and second photographed images 124 displayed on the first and second display areas 122 and 123, respectively. , 125 is displayed.

  When the Fn button 114 is pressed while the first and second photographed images 124 and 125 are displayed, only one photographed image is displayed.

  Next, the image reproduction process will be described in detail with reference to FIG. The image reproduction process is executed when the reproduction button is pressed.

  In step S61, the captured image is displayed on the display screen 121. In step S62, it is determined whether the rear operation dial 112 or the cross key 113 has been operated. When operated, the process executes step S63, and when not operated, the process moves to step S64 without executing step S63. In step S63, a scaling movement process described later is performed.

  In the next step S64, it is determined whether or not the second captured image 125 has been selected. Selection of the second photographed image 125 is performed using the cross key 113. When the second captured image 125 is not selected, the process moves to step S65, and when selected, the process moves to step S61.

  In step S65, it is determined whether or not the Fn button 114 has been pressed and the user has selected simultaneous display of the first and second captured images 124 and 125. When the user selects the simultaneous display, the simultaneous display process described later is executed in step S66. If not selected, it is determined in step S67 whether or not to end the reproduction process. When the digital camera 100 shifts to the shooting mode by pressing the release button 111, when the power of the digital camera 100 is turned off, it is determined that the reproduction process is finished, and the reproduction process is finished. The shooting mode is an operation state that is set when the digital camera 100 captures a subject. If it is not determined that the process is to be terminated, the process returns to step S62.

  Next, the scaling movement process will be described with reference to FIG. The variable magnification movement process is executed in step S63 of the reproduction process.

  First, in step S71, it is determined whether or not an enlargement operation has been performed. That is, it is determined whether or not the rear operation dial 112 has been rotated rightward. When the enlargement operation is performed, the captured image is enlarged in step S72, that is, the display magnification is increased by one step. If the enlargement operation is not performed, step S72 is not executed and the process proceeds to step S73.

  Next, in step S73, it is determined whether or not a reduction operation has been performed. That is, it is determined whether or not the rear operation dial 112 has been rotated leftward. When the reduction operation is performed, the captured image is reduced in step S74, that is, the display magnification is reduced by one step. If the reduction operation is not performed, step S74 is not executed and the process proceeds to step S75.

  In step S75, it is determined whether or not a moving operation has been performed. That is, it is determined whether or not the cross key 113 has been operated. When the moving operation is performed, it is determined in step S76 whether or not the display area can be moved in the direction instructed by the cross key 113. That is, it is determined whether or not the captured image has reached the movement limit position. If the display area can be moved, the process moves to step S77, moves the display area, and moves to step S78. If the display area cannot be moved, the process moves to step S78 without moving the display area. In step S78, the scaling movement process is terminated, and the process returns to step S64 of the reproduction process.

  Next, the simultaneous display process will be described with reference to FIG. The simultaneous display process is executed in step S66 of the reproduction process.

  In step S81, it is determined whether or not the captured image to be displayed is only a vertically captured image. In the case of only the vertically shot image, in step S82, the minimum display magnification of the shot image is set to 0.75 times or more, and the shot image is displayed in the first and second display areas 122 and 123 at 0.75 times or more. Is done. In the case where only the horizontally shot image is present, or when the vertically shot image and the horizontally shot image are mixed, in step S83, the minimum display magnification of the photographed image is set to 1 or more, and the photographed image is 1 or more times and the first and They are displayed in the second display areas 122 and 123, respectively.

  Next, in step S84, it is determined whether or not the captured images displayed in the first and second display areas 122 and 123 have been changed. When the captured image is changed, the procedure returns to S81. As a result, the display magnification of the captured image displayed in the first and second display areas 122 and 123 is adjusted again. When the captured image is changed, the newly displayed captured image is displayed at the same magnification as the captured image that has been displayed so far. That is, when the display magnification of the captured image that has been displayed so far is 16 times, the newly displayed captured image is displayed at 16 times.

  If the captured image is not changed, the procedure proceeds to step S85. In step S85, it is determined whether or not both the first and second display areas 122 and 123 are selected. If both are selected, the process proceeds to step S86. When both are not selected, only one display area is selected, so the process proceeds to step S70, and the zooming movement process is executed on the captured image displayed in the selected display area. After the scaling movement process is executed, the process returns to step S85.

  Next, in step S86, it is determined whether to perform enlargement / reduction. This determination is made based on whether or not the rear operation dial 112 has been operated. If operated, the simultaneous scaling process described later is executed in step S87, and the process proceeds to step S88. If not operated, the process proceeds to step S88 without executing step S87.

  In step S88, it is determined whether or not the display area is moved. This determination is made based on whether or not the cross key 113 is operated. When the cross key 113 is operated, a simultaneous movement process, which will be described later, is executed in step S89, and the process proceeds to step S90. If not operated, the process proceeds to step S90 without executing step S89.

  In step S90, the simultaneous display process ends, and the process returns to step S66 of the original process, that is, the reproduction process.

  Next, the simultaneous scaling process will be described with reference to FIG. The simultaneous scaling process is executed in step S87 of the simultaneous display process.

  In step S91, it is first determined whether the display magnification change is enlargement or reduction. The determination is made based on whether the rear operation dial 112 is rotated left or right. When the image is rotated leftward, the change in display magnification is determined to be reduced, and when it is rotated rightward, the change in display magnification is determined to be enlarged. When it is enlargement, the process proceeds to step S92, and when it is reduction, the process proceeds to step S93.

  In step S92, it is determined whether one or both of the two captured images displayed in the first and second display areas 122 and 123 are actually displayed at the maximum magnification. If not displayed at the maximum magnification, the process proceeds to step S94. In step S94, the display magnification of the two captured images displayed in the first and second display areas 122 and 123 is increased by one step. Thereby, two captured images are enlarged simultaneously.

  In step S93, it is determined whether one or both of the two captured images displayed in the first and second display areas 122 and 123 are actually displayed at the minimum magnification. If not displayed at the minimum magnification, the process proceeds to step S95. In step S95, the display magnification of the two captured images displayed in the first and second display areas 122 and 123 is decreased by one step. As a result, the two captured images are simultaneously reduced.

  When one or both of the photographed images are currently displayed at the maximum magnification in step S92, that is, for example, when any one of the photographed images reaches 32 times, the display magnification of the two photographed images is not increased. If the display magnification of the first captured image 124 is 16 times when the display magnification of the second captured image 125 is 32 times, the first captured image 124 is not enlarged beyond 16 times.

  In addition, when one or both of the captured images are actually displayed at the minimum magnification in step S93, that is, for example, when one of the captured images reaches 0.75 times or 1 time, the two captured images are displayed. The display magnification is not reduced. If the display magnification of the second photographed image 125 is 1.7 times when the display magnification of the first photographed image 124 is 0.75 times, the first photographed image 124 is from 1.7 times. Is not reduced.

  Thus, when either or both of the captured images are currently displayed at the maximum or minimum magnification in step S92 or step S93, the process proceeds to step S96 without changing the display magnification of the two captured images.

  When steps S94 and S95 are completed, the process proceeds to step S96. In step S96, the process returns to the simultaneous display process.

  Thereby, two captured images are enlarged or reduced simultaneously.

  Next, the simultaneous movement process will be described with reference to FIG. The simultaneous movement process is executed in step S88 of the simultaneous display process.

  In step S <b> 101, it is first determined whether or not the first captured image 124 can be moved in the movement direction input by the cross key 113. When it is determined that the movement is possible, that is, when the first captured image 124 has not reached the movement limit position of the first display area 122, the process proceeds to step S102. When it is determined that the movement is not possible, that is, when the first captured image 124 has reached the movement limit position of the first display area 122, the process proceeds to step S103.

  In step S102, it is determined whether or not the second captured image 125 can be moved in the movement direction input by the cross key 113. When it is determined that movement is possible, that is, when the second captured image 125 has not reached the movement limit position of the second display area 123, the process proceeds to step S104. When it is determined that the movement is not possible, that is, when the first captured image 124 has reached the movement limit position of the first display area 122, the process proceeds to step S105.

  In step S104, the first and second display areas 122 and 123 are moved in the movement direction input by the cross key 113. In step S105, the first display area 122 is moved in the movement direction input by the cross key 113.

  In step S103, it is determined whether or not the second captured image 125 can be moved in the movement direction input by the cross key 113. When it is determined that the movement is possible, that is, when the second captured image 125 has not reached the movement limit position of the second display area 123, the process proceeds to step S106. When it is determined that it is not movable, that is, when the first captured image 124 has reached the movement limit position of the first display area 122, the first and second display areas 122 and 123 are not moved. The process proceeds to step S107.

  In step S <b> 106, the second display area 123 is moved in the movement direction input by the cross key 113.

  When steps S104, S105, and S106 are completed, the process proceeds to step S107. In step S107, the process returns to the simultaneous display process.

  This makes it easy to refer to the image displayed on the display device.

  Next, an embodiment of an image display system according to the present invention will be described with reference to the accompanying drawings. FIG. 11 is an external view of a digital camera to which an imaging lens is attached and an external display device.

  The digital camera 100 includes an output terminal 141. The external display device is a television 190, for example. The television 190 includes an input terminal 191 that can receive a composite video signal. A signal cable 195 is connected to the output terminal 141 and the input terminal 191.

  A captured image displayed on the display device 120 using the above-described reproduction processing, scaling movement processing, simultaneous display processing, simultaneous scaling processing, and simultaneous movement processing in the digital camera 100 is output from the output terminal 141 as a composite video signal. Output. The composite video signal is transmitted to the input terminal 191 through the signal cable 195. The television 190 that has received the video signal via the input terminal 191 displays a captured image on the external display screen 192.

  Thereby, the user can refer to the image using the external display screen 192 having a larger display area than the display screen 120.

  Note that the signal output from the output terminal 141 may be any signal that can transmit an image such as an S video signal, a component video signal, or an RGB signal. When an S video signal is output, the signal cable is connected to an S video input terminal of a television, for example. When RGB signals are output, the signal cable is connected to, for example, an RGB input terminal of a computer display.
